Looks like a messy job in my opinion.
Hugues: That was very informative. It clearly shows it's not worth the effort. "

Looking forward to your maiden ride!!

Thanks for the AXE controller... this bike works well , just a bit on the heavy side.

" Hey Noah... i like your design idea as I went a different route to keep the Leaf modules weather-proofed.
My idea was to incorporate a stressed member of the frame, aka "box". The main disadvantage of my route is the redundancy of the sardine cans= extra unnecessary weight.
I know the battery pouches need to be compressed. I'm toying with the idea of opening up all of the modules to remove the pouches and then making a compression plate out of Al on one side of the pouch stack, and putting a modified motorcycle tire inter-tube on the other side of the compression plate. The pouches can be compressed with whatever air pressure is needed in the inter tube.
The main advantage of my design is the ability to switch to a different battery chemistry whenever that day arrives.

My main questions about removing the pouches from the sardine cans is how much weight can be shaved off and if any additional space for more pouches will be created, besides how challenging it is to remove them without damaging them. Any experience? If anyone has experience with this, please chime in!

" Austin was fantastic. Between MotoGP and the Handbuilt Motorcycle Show I hardly had time to think.
I spent a good portion of each day extolling the virtues of elmoto.net and the community support here which made it possible for anyone (even me!) to convert an electric motorcycle. Everyone was very enthusiastic and had lots of questions. All the builders were supportive, and I came away incredibly inspired for the next project!https://uploads.tapatalk-cdn.com/201...7ad9a5810a.jpg

Be sure to give us a report when you return and good luck with the weather. "

" Just like the last 100 years...we are still waiting for the battery to match gas. It isn't going to happen. The physics don't allow it. But we can get close enough. This guy runs a battery research lab. He is not as hopeful as most of us. But then, he knows what he is talking about.

He, like most researchers, are puzzled, but hopeful, for the performance claims of the new Goodenough battery. If it is actually working as claimed, there is some new/unexpected stuff going on. I certainly hope it works. As much as I appreciate current li-ion batteries, using them, you know all the frustrating limitations. "

" An update on this:

Back in late February John Goodenough announced just such a breakthrough in battery technology. The new tech can use Lithium or Sodium and hold at least 3X the density of current Lithium batteries. They were very robust during fast charge and repeated charging because they use a glass (not liquid) electrolyte and cannot form power-sucking dendtrites as the alkali metal moves from anode to cathode. A good article from March 17 is here:

https://www.forbes.com/sites/jamesco...etting-better/

And here is an update in an online Q&A from April 19:

https://hardware.slashdot.org/story/...n-b-goodenough

There are some details in there that might interest readers on ElMoto. I will summarize some of them:

  • Lower temperature operation: -20C (-4F)
  • Less heat generation during charg and discharge
  • Faster to charge
  • More recharge cycles with less degredation (maybe almost zero)
  • Cheaper to manufacture
  • Easier to recycle
  • Goodenough estimates three years for a large battery manufacturer to have a working factory

" Thanks! It's a good feeling knowing it's now legal - the rest is just tinkering and making it better!
The bearings - looks like it was just a duff one - I took the bearing completely apart after removal, to see what state it was in - firstly there was no grease in it at all, the inner and outer races showed no signs of any damage and likewise under a magnifying glass it was hard to see any damage to the balls, but, rolling them on a flat sheet of glass did reveal that they had flats on them, which is where I was getting the notchiness. The other side bearing was actually filled with grease and was not notchy at all but had some lateral play so was replaced also. The bearings are 61912 ZZ measuring 85mm Outer 60mm Inner and 13mm width.
I only got it finished last night so have only run it on the paddock stand, should get time this weekend to run a couple of full charges through it and get some real world stats.
Cheers,
Mike. "
